# E-scripts on Squeak (not on other SmallTalks)
#
# Note 1: use the eev command (defined in eev.el) and the
# ee alias (in my .zshrc) to execute parts of this file.
# Executing this file as a whole makes no sense.
# An introduction to eev can be found here:
#
# (find-eev-quick-intro)
# http://angg.twu.net/eev-intros/find-eev-quick-intro.html
#
# Note 2: be VERY careful and make sure you understand what
# you're doing.
#
# Note 3: If you use a shell other than zsh things like |&
# and the for loops may not work.
#
# Note 4: I always run as root.
#
# Note 5: some parts are too old and don't work anymore. Some
# never worked.
#
# Note 6: the definitions for the find-xxxfile commands are on my
# .emacs.
#
# Note 7: if you see a strange command check my .zshrc -- it may
# be defined there as a function or an alias.
#
# Note 8: the sections without dates are always older than the
# sections with dates.

Hi Vanessa!
Thanks! =) This works in a workspace,

"Two ways of toggling the switch after 1000ms:"

but this doesn't:
bm2 := SimpleButtonMorph new.
bm2 target: bl.
bm2 actionSelector: #value.
bm2 addAlarm: #doButtonAction after: 1000.
What is the right way to add an alarm to a morph that is not shown on
the screen? Also, can I create a new invisible morph every time that I
want to run an alarm? Are they going to be garbage collected?
Thanks in advance!

...here are the details.
I clicked on the Help menu,
then used the halo twice to select just the line in it
that says "Keyboard Shortcuts",
then I duplicated it...
and I got a menu with just one item -
"Keyboard Shortcuts".
I use the halo on it
and then the wrench
and I get a menu
whose fourth option is "Explore Morph".
I choose that and
I get an explorer
whose title is: a MenuMorph<Menu>(1170696)
I open submorphs -> 1 -> extension,
and I get this...
the fields in red look promising -
let me send a screenshot first -
https://i.ibb.co/xh77cy6/sshot.png
http://anggtwu.net/tmp/squeak-2023jan27-question1.png
and then let me see if I can discover
how to use the symbol #commandKeyHelp
in submorphs -> 1 -> selector...
hmm, my problem now is to find an object xxx
such that running
xxx commandKeyHelp
would open the "Keyboard Shortcuts" menu.
I used the search bar on commandKeyHelp
and I found that there is one "implementor" for that method...
and I got these two expressions that
I can put in a workspace and execute with C-d,
and that would open system browsers in the right places...

Okay!
SmalltalkEditor.st 14.0 KB
I had to remind myself of a lot of things (it's been years)
sorry it took so long
Okay download this, then in your Squeak:
Tools menu, select File List
and browse to where you downloaded this file
Click it, then click the filein button
Okay cool
One last step
Go to the tools menu and open a workspace and a transcript
in either of them:
SmalltalkEditor initialize
and hit C-d
Now here's what should happen: C-e should inject the contents of /tmp/emacs-squeak.txt and point; C-E should write the selection to the same file
So you could test by selecting some text and hitting C-E, then seeing whether that file exists from Emacs
(and if so, editing it there, saving, and hitting C-e in the workspace)
you should see a little notification in the Transcript
FANTASTIC!!!
Does it work?
Perfectly!!!!!!!!!! =) =) =)
Yay
If you want separate files that's a trivial change
No, it's better that way!!!
one last thing: try C-d on "SmalltalkEditor browse" (no quotes) and ensure the instance (rather than class) button is clicked
look for methods emacsIn and emacsOut
FWIW the time consuming thing here was figuring out how to rebind, and looking at the editor API to see how to grab the selection or insert at point
It's probably been 17 years since I dug around the system in this way so I've forgotten everything

Hi list,
first some context:
I was trying to put some blocks of executable notes in something
like the "Terse Guide to Squeak"... the Terse Guide is implemented
as a class called TerseGuideHelp, and I was working on a modified
copy of that class, that I called EdrxGuideHelp... but then I saw
that the window that shows the content of a topic in a help browser
treats local variables in a way that is different than the one in
workspaces - if I run "a := 42" in the window with the contents of a
topic I get a dialog window whose title is:
Unknown variable: a!
please correct, or cancel:
Now a more basic question. I sort of know where the "local variables"
of a workspace are stored... if I start with a single workspace and I
run this on it,
w := Workspace new.
w buildAndOpen.
and then I run this on the second workspace,
a := 2.
b := a + 3.
and then go back to the first workspace and "print it" this,
w bindings.
I get:
a Dictionary('a'->2 'b'->5 )
My first guess was that "do it"s and "print it"s in a workspace use
a dictionary of bindings, but "do it"s and "print it"s in the
mini-workspace of a help browser do not. I tried to understand
"real" workspaces first, and after setting a breakpoint in
TextEditor >> #printIt
and doing lots of single-steppings I arrived at this method,
TextEditor >> #evaluateSelectionAndDo:
that has this:
result := [
rcvr class evaluatorClass new
evaluate: self selectionAsStream
in: ctxt
to: rcvr
environment: (model environment ifNil: [Smalltalk globals])
notifying: self
ifFail: [self flash. ^ nil]
logged: true.
]
on: OutOfScopeNotification
do: [ :ex | ex resume: true].
but when that code calls this method
Compiler >> #evaluate:in:to:environment:notifying:ifFail:logged:
the "rcvr class evaluatorClass new" is simply a "Compiler new", "self
selectionAsStream" is "a := 2. b := a + 3." as a stream, the ctxt and
the rcvr are nil, and the environment is just "Smalltalk"... where
does the dictionary of local bindings enter the story? Am I doing
something wrong in the debugger?...
Thanks in advance!

Hi Karl,
> In HelpBrowser you must declare the variables before using them.
> (...)
> HelpBrowser does not implement dynamic binding of variables.
Yes - my first idea was to ask here what I needed to change in my
class TerseGuideHelp to make the "workspace" of its help browser use
dynamic biding of variables... but then I spent some hours trying to
find the answer myself, and I stumbled on a more low-level question
that I found much more askworthy...
> You can right click on a Workspace window and a HelpBrowser window
> and inspect the model and see the differences.
I did that. Are these differences obvious to a trained eye? They
weren't to me.
> Also browse class Workspace and look at access to variable
> 'bindings'.
This may be a pointer to searching tools that I need to learn. I saw
that if I click on "variables" and then on "bindings" I get a list of
the methods in Workspace that access the variable "bindings"... I also
tried to fileOut the class Workspace and to read it in Emacs, and I
found the same occurrences.
Here is an educated guess. Is the method "hasBindingOf:" the main
piece needed to make a mini-workspace support dynamic variables? If
so, how, exactly? Is there a part of the compiler that calls
"hasBindingOf:" when it sees an unknown variable? I couldn't find
it...
Cheers,
Eduardo Ochs

# hb := HelpBrowserB openOn: TerseGuideHelp. hb model. --> a HelpBrowser
Hi list,
earlier today, in this other thread,
http://lists.squeakfoundation.org/pipermail/squeak-dev/2023-February/223584.html
I was trying to create a subclass of HelpBrowser, called HelpBrowserB,
that would behave in a slightly modified way... to make things trivial
to test, suppose that we create it like this:
HelpBrowser subclass: #HelpBrowserB
instanceVariableNames: 'bindings'
classVariableNames: 'LookupPools'
poolDictionaries: ''
category: 'Category-Edrx'
Then if we run this with "print it",
hb := HelpBrowserB openOn: TerseGuideHelp.
hb model.
the result is "a HelpBrowser", not "a HelpBrowserB".
Is that intentional or a bug?
Thanks in advance!

is, where it lives, and how it relates to its environment? Do you
know the meaning of life? Do you want to impress your friends and
confuse your enemies? Well, this talk only covers Morphic, for the

Hi list,
I asked this question here on the list a few days ago,
http://lists.squeakfoundation.org/pipermail/squeak-dev/2023-February/223398.html
on how to write code that _sends_ certain keyboard events. I think
that I got a prototype of an answer for it, that "just" needs some
debugging... and then I started to work on ways to debug my prototype.
The ideal way to test sending keyboard events would be to have some
code that _receives_ and _handles_ keyboard events, and that runs
things like "Transcript show: evt" or "evt halt" when it receives a
keyboard event. I tried to adapt the code from these wiki pages
https://wiki.squeak.org/squeak/1125 Programming Morphs (Active Essay)
https://wiki.squeak.org/squeak/1216 Programming morphs - page 7 - keyboard events
https://wiki.squeak.org/squeak/3503 Morphic Key Events
without much success, and I also tried to modify the keyboard
exerciser - i.e., this:
"World menu -> objects (o) -> Categories -> Demo -> Exercise Keyboard"
KeyboardExerciser new openInWorld.
...and then I saw a way to play with keyboard handlers that does not
require creating any classes or modifying any methods, and that can be
run entirely from a workspace with "do it"s and "print it" in the
right places. It is here:
"The first lines were adapted from:
https://wiki.squeak.org/squeak/2188 PolygonMorph"
a := Array with: 50@100 with: 200@300 with: 100@400.
b := (PolygonMorph
vertices: a color: Color red
borderWidth: 1 borderColor: Color black).
World addMorph: b.
b beSmoothCurve.
b beStraightSegments.
b vertices.
b vertices at: 1.
b vertices at: 1 put: 40@100.
b vertices at: 1 put: 50@100.
b vertices at: 1 put: 40@100. b computeBounds.
b vertices at: 1 put: 50@100. b computeBounds.
a at: 1 put: 40@100. b computeBounds.
a at: 1 put: 50@100. b computeBounds.
b color.
b color: Color banana.
b color: Color fern.
b color: Color red.
e := EventHandler new.
b eventHandler.
b eventHandler: nil.
b eventHandler: e.
Now how do I change that event handler in interesting ways?
Does this make sense?
e on: #keyStroke send: #halt to: b.
Also, is there a way to transfer the keyboard focus to the
PolygonMorph with a "do it" in that workspace? I guess that we
need to run the method #newKeyboardFocus:, but how exactly?
Anyone has examples to share?

How do I create a "synthetic" keyboard event?
Hi list,
this is a follow-up to these two messages:
http://lists.squeakfoundation.org/pipermail/squeak-dev/2023-February/223407.html
http://lists.squeakfoundation.org/pipermail/squeak-dev/2023-February/223408.html
The first one was a question that I asked, and the second was an
answer by Marcel Taeumel. I was able to decypher almost all his
pointers - but not yet this one:
HandMorph >> #generateKeyboardEvent:
I am using this code:
a := Array with: 50@100 with: 200@300 with: 100@400.
b := (PolygonMorph
vertices: a color: Color red
borderWidth: 1 borderColor: Color black).
World addMorph: b.
b beSmoothCurve.
b beStraightSegments.
b vertices.
b vertices at: 1.
b vertices at: 1 put: 40@100.
b vertices at: 1 put: 50@100.
b vertices at: 1 put: 40@100. b computeBounds.
b vertices at: 1 put: 50@100. b computeBounds.
b color.
b color: Color banana.
b color: Color red.
e := EventHandler new.
b eventHandler.
b eventHandler: nil.
b eventHandler: e.
bl := [ :a :b | { a . b }].
bl := [ :a :b | Transcript show: { a . b }; cr. ].
bl numArgs.
bl value: 2 value: 3.
bl perform: #value:value: with: 2 with: 3.
bl := [ :evt :sm | Transcript show: { evt . sm }; cr. ].
bl := [ :evt :sm | Transcript show: { evt keyValue . sm }; cr. ].
bl := [ :evt :sm | self halt. ].
e on: #keyStroke send: #value:value: to: bl.
b currentHand newKeyboardFocus: b.
It is meant to be used in a workspace. By selecting the right parts of
it and running them with "do it"s or "print it"s in the right order I
can create a PolygonMorph, some EventHandlers, and some blocks, and
then I can make the PolygonMorph react to keyboard events in different
ways. The last line switches the keyboardFocus to my PolygonMorph, and
then I can send several keystroke events to my PolygonMorph, and
inspect their events either on the transcript or on the debugger.
Question: suppose that evt is an event whose printed representation is
this one:
[79@273 keystroke ' ' (32) 956759]
I know that this means that:
evt position -> 79@273
evt type -> #keystroke
evt keyValue -> 32
evt keyCode -> 32
evt source -> self currentHand
evt timeStamp -> 956759
How do I write code that creates an event like that? I would like to
create, ahem, "synthetic keystrokes", and experiment with sending them
to certain morphs...
Thanks in advance!

Hi Karl,
ouch, so my plan is completely wrong... it was roughly this: 1) learn
how to create synthetic keyboard events, 2) learn how to send these
events to morphs with the debugger turned on, 3) use that to find the
actions associated to typing certain keys in certain places, 4) become
less of a beginner...
I installed your two .mczs and tried this,
EventRecordingSpace open
and I got this error after just a few keys and mouse clicks:
MouseButtonEvent(Object)>>doesNotUnderstand: #eventType
I also took a look at the snapshot/source.st in the .mcz with Emacs
(!!!). I search for "keyboardevent" there case-insensitively, and
found very few occurrences - and none of them very enlightening...
"keystroke" has lots of occurents, but same.
Can I ask you for some suggestions and hints?
a) How do you do my (3) above, i.e., "use that to find the actions
associated to typing certain keys in certain places"?
b) I've tried to learn Etoys, but many links are broken, many
packages too, the mailing lists and forums look dead, and the
tutorials that I could access feel very incomplete to me... for
example, the link [1] below only has the videos 1, 10, 20, and
30, [2] has lots of steps that took me many hours to decypher,
and [3] shows ways to script and connect etoys that I don't have
any idea how to do myself... when you convince people to learn
Etoys what are the resources - including forums and mailing lists
- that you recommend?
Thanks in advance...

How do I translate "sendKeyboardEvent: CR" to real code?
Hi list,
suppose that I am exploring a morph and want to use the debugger to
understand what happens when I send a CR to one of its submorphs. I
guess that a good way to do that would be to run a one-liner like this
in the explorer window,
42 halt. (self submorphs at: 1) sendKeyboardEvent: CR.
but this is just pseudo-code, of course... I've spent some hours on
the swiki and browsing the source code of methods and classes that
looked promising, like these ones,
EventSensor>>#processKeyboardEvent:
HandMorph>>#generateKeyboardEvent:
HandMorph>>#sendKeyboardEvent:
KeyboardEvent
but I couldn't find any code that generates a keyboard event itself
and sends it to a morph... I know how to add a breakpoint to a
keyDown: method, but debugging that breakpoint would start the
debugger in a place in which a keyboard event had already been
generated, and is being processed - and I'm looking for a way to do
something that is several steps before that (break)point.
Any hints? Translations of the "sendKeyboardEvent: CR" above to real
code - either low-level or high-level - would be ideal, but links
can help me a lot too, of course...
Thanks in advance!

Hi list,
I'm trying to port to Squeak an idea that use a lot in Emacs, that is
to use one-liners as hyperlinks. There's a page with a detailed
explanation of that idea in this link,
http://anggtwu.net/eev-squeak.html
and here goes a short explanation, and a question.
I'm working on a class called "See", and my one-liners that work as
hyperlinks always start with "See". For example, these ones
See class: HelpBrowser.
See class: HelpBrowser method: #accept:.
See class: See.
See class: See classMethod: #item1ctsa:.
See class: See classMethod: #class:method:.
See class: See classMethod: #class:classMethod:.
make the SystemBrowser display different pieces of information, and
these one liners
See fileList.
See helpBrowser.
See messageNames.
See methodFinder.
are equivalent to running:
Tools -> File List
Apps -> Help Browser
World -> open -> message names
World -> open -> method finder
but there are LOTS of menu entries that I don't know how to implement
as one-liners, because their "targets" are objects that I don't know
how to access from "global code"... let me explain this.
When I run "See methodFinder" it runs this: "ECToolSet
openSelectorBrowser". I discovered that the "action" associated to
"World -> open -> method finder" is "ECToolSet openSelectorBrowser" by
using the halo to duplicate the entry "method finder" in the menu
"World -> open", and then I examined the "contents", the "target", the
"selector", and "arguments" of that first item of that menu with just
one entry. Here is a visual explanation in a screenshot,
http://anggtwu.net/IMAGES/2023-squeak-item1ctsa.png
and in that case my function that returns the fields "contents",
"target", "selector", and "arguments" of a menu item returns this:
{'method finder' . ECToolSet . #openSelectorBrowser . #()}
When I try to do the same for "Help -> Squeak help" I get:
{'Squeak Help' . a TheWorldMainDockingBar . #squeakHelp . nil}
note the "a"... =(
When I run this to try to find a global variable that holds an object
of the class TheWorldMainDockingBar,
Smalltalk globals keysAndValuesDo: [:k :v |
(v isKindOf: TheWorldMainDockingBar) ifTrue: [ Transcript show: k; cr. ]
].
it returns nothing. So I wrote these two methods in my class "See" to
help me find active morphs of a given class,
--snip--snip--
!See class methodsFor: 'other links' stamp: 'Edrx 2/1/2023 00:55'!
worldMorphs
"Return an OrderCollection with all the morphs whose world is non-nil.
Test:
See worldMorphs explore.
"
^ Morph allSubInstances select: [ :m | m world notNil ].
! !
!See class methodsFor: 'other links' stamp: 'Edrx 2/1/2023 00:57'!
worldMorphs: class
"Return an OrderCollection with all the morphs whose world
is non-nil, and that are objects of the given class.
Test:
(See worldMorphs: DockingBarItemMorph) explore.
"
^ Morph allSubInstances
select: [ :m | (m world notNil) and: [m isKindOf: class] ]
! !
--snip--snip--
but for the class TheWorldMainDockingBar this one-liner
(See worldMorphs: TheWorldMainDockingBar) explore.
returned no instances...
Any suggestions?
Thanks in advance,

During recording, the EventRecorder subscribes to all events of the
normal morphic hand, and saves them as they occur.
For replay, a second playback hand is created that reads events from
the recorder and plays them back in the world.
The EventRecorder began with the work of Ted Kaehler and John Malone.
This was then signifcantly expanded by Leandro Caniglia and Valeria
Murgia as a tutorial aid for the Morphic Wrapper project.
Since that time, I have...
Changed to a simple inboard array for the tape (event storage).
Provided the ability to condense linear mouse movement with interpolation at replay.
Made simple provisions for wrap-around of the millisecond clock.
Eliminated step methods in favor of using the processEvents cycle in the playback hand.
Provided a pause/resume mechanism that is capable of surviving project changes.
Added the ability to spawn a simple 'play me' button that can be saved as a morph.
Caused the playback hand to display its cursor double size for visibility.
Integrated a voice recorder with on-the-fly compression.
This currently does NOT survive project changes, not is its data stored on the tape.
Right now it can only be saved by saving the entire recorder as a morph.
This will be fixed by adding a startSound event at each project change.
We will also convert read/write file to use saveOnFile.
Added a journal file facility for recording sequences that end in a crash.
The above two features can be engaged via the ER's morph menu.

How do I "sleep 5"?
Hi list,
a few days ago I asked for help on how to send a "synthetic" keyboard
event to a morph, and Karl Ramberg gave me exactly the right hints in
this thread:
http://lists.squeakfoundation.org/pipermail/squeak-dev/2023-February/223473.html
My code is ready except for documentation and comments - I'll work on
that in the next few days and then post the result here and on the
wiki...
...but there's a feature that I want to add to it that - again =( -
needs something that I'm not being able to discover by myself. How do
I write a line of code that waits for 5 seconds, sort of like running
"sleep 5" in a shell, and that doesn't block the rest of the system?
If I have that I'll be able to run these two lines in a workspace,
self mySleep: 5000.
kf := self currentHand keyboardFocus.
switch the keyboard focus to something else by clicking on it, and
then the variable kf will be set to this "something else"...

Hi list,
I need to ask for more pointers... =(
Now I know how to debug what happens when I send certain keys to
certains morphs. My code is here - not on the wiki yet, sorry -
http://anggtwu.net/eev-squeak.html#key-events
and I am using that to learn how lots of things work. But the morphs
seem to fall in several different families, each one with a different
way of initializing... for morphs like these ones I can just use
openInWorld,
sm := SimpleSwitchMorph new.
sm openInWorld.
bm := SimpleButtonMorph new.
bm openInWorld.
bm position: bm position + (0@32).
rm := RectangleMorph new.
rm openInWorld.
rm position: rm position + (0@64).
but for SelectorBrowser I need to use "prototypicalToolWindow" instead
of new, and there are other ones, like SearchBar, that I don't know
how to create a new morph of that kind...
Where can I learn more about that? And where do people usually learn
how to create interfaces in which a single window displays several
subwindows and subwidgets? In Tcl/Tk this is considered basic... here
is an example of this "this": the code below
frame .top
frame .bottom
text .textbox -width 10 -height 5
listbox .listbox -width 10 -height 5
button .button1 -text B1
button .button2 -text B2
button .button3 -text B3
.textbox insert end "Foo\nBar"
.listbox insert end "Item 1"
.listbox insert end "Item 2"
.listbox insert end "Item 3"
pack .top -side top
pack .bottom -side bottom -fill x -expand 1
pack .listbox -side left -in .top
pack .textbox -side right -in .top
pack .button1 -side left -in .bottom -fill x -expand 1
pack .button2 -side left -in .bottom -fill x -expand 1
pack .button3 -side left -in .bottom -fill x -expand 1
creates the window in this screenshot:

Thanks in advance! =)

IRC chat, 2006aug11:
<gulik> edrx: Try this in a Squeak workspace: (1 to: 100) collect: [ :each | each * 2 ].
<gulik> Select it and press alt-i.
<gulik> Its a stupid bit of code that returns a list of numbers.
<gulik> Here's a better example that shows how inspectors update:
<gulik> Make a list: myList := OrderedCollection new.
<gulik> Add stuff to it: 1 to: 100 do: [ :each | myList add: each ].
<gulik> select only "myList" and press alt-i.
<gulik> and then change it: myList at: 1 put: 'hello'.
<gulik> You should see it change in the inspector.
<gulik> The debugger is pretty cool as well. Some people advocate coding using only the debugger.
<gulik> That is, write some code, run it until it fails, write more code to make it not fail and "continue" the debugger until it fails again.
